B20vtec GSR Cam Rebuild Series part 1: The Start and The Plan

On this first installment of the series we do the usual, compression test before disassembly.
Watch along to find out what we found and the cause of such issues
The plan for the build and target potential as well as a tip on identifying B16a pr3 head cores.
Current Set-Up is
B16a pr3 ported head on ITR dual springs
B18c1 GGSR cams
ITR intake manifold
(soon to be skunk2 pro series ported)
1UP pistons w/ ARP rod bolts stock rods
As mentioned in the video on bearing wear and causes here is episode 2 of the Civic SiR series that talks about this further

The importance of parts and block cleanin prior to final assembly has been mentioned and a video pertaining to such topic is here

love the work u do on any honda engine

[@SRDmotorsports]

Thank you brother! I appriciate that you enjoy the work we share!

[@renesandoval7515]

When you putting in the crank in the block can you show thrust washer install plz thanks👌 keep up the good work

[@SRDmotorsports]

Yeah could do that no prob sir! Thank you

[@blue3549]

Good visual demonstration of valve leak i can already tell this refresh is going to be good

[@SRDmotorsports]

yeah was surprised it leaked almost instantly and yeah the fun begins indeed :)

[@peterbryant3584]

Great content ur the best u make it sound so simple 👌

[@SRDmotorsports]

Thank you man! I guess a lot try to make it sound complicated so they don’t get copied… but sharing is sharing And for me? Being copied is fine it’s just another reason for me to try to be even better once again

Yes sir! Fellow b20vtec owner! But u got a better cam 😎

[@BenjieCoB20VTEC]

@@SRDmotorsports what valves are you going for?

[@SRDmotorsports]

@@BenjieCoB20VTEC really depends on owner budget but the japan replacement is the most cost friendly ones the “Dokuro” brand

[@BenjieCoB20VTEC]

@@SRDmotorsports yeah.. the one that comes with the blue box. Already used that when i had the ph16 engine, decades ago..

@@BenjieCoB20VTEC I think later on they changed color boxes lol but yes sir same here back with my old Hatch, I ran dokuro and that included 20+ events in Clark and more than 50 dyno tests it held up fine

Hey Paco atleast ur comp is good 😂

[@carlosvidal3480]

Quick question for you, I’m going to send my b18c1 to be refreshed and I want to make more power this time since you are not coming to the US anytime soon! What’s a good combination of compression and bore for b18c1 , I’ll be using stock head and cams, I can have it sleeve if needed, the head will be street ported this time, also it will be tune on 93, I also have a stock b20 block if you think b20 block will be better! Thanks for having this amazing channel, your builds are incredible!

[@SRDmotorsports]

I think for a 93oct fuel target that sounds good Stock head and cams just means u safer with no more than 11.2:1 comp so that’s easy for u and the street port will def be of big help The displacement will always have an edge so a 2.0 will be nice and since it’s a stock cam? The valves won’t be in so much danger on stock b20 pistons (the pockets are off for vtec) so that could be all good This then can let u save the b18c1 block for future plans or turbo hmmmm

[@carlosvidal3480]

@@SRDmotorsports it was turbo already and I’m changing back to NA because I will be circuit tracking now, I was thinking to sleeve and bore to 84mm with supertech pistons, high comp? I might be able to get cams too if needed but still at 93 gas? What do you think?

[@carlosvidal3480]

It’s got springs and retainers for skunk and edelbrok intake manifold

[@carlosvidal3480]

I forgot eagle rods too

[@SRDmotorsports]

@@carlosvidal3480 if it’s a b18c1 sleeved it would def be stout and good for track use

[@renwod576]

Good video. Great content. Very informative. Been liked and subscribed for a while and I like doing this old b series stuff myself. Eager for breather system on b20v as there is only on valve cover.

[@SRDmotorsports]

Thank you my friend for checking it out! And yes we will progress with more “stuff” next

[@mayk3lll]

Could it be from valve lash neglect in thr 5yrs of ownership?

[@SRDmotorsports]

if it’s valve lash let’s say 0.007” intake and it got big to 0.012” It’s still too small to actually hit anything and if it did hit? The mark on the pockets will be more than just “carbon” markings Next episode will have more goods 😎

[@mayk3lll]

@SRDmotorsports thank you for the insight. I'm a new subscriber, loving the info you put out.

[@SRDmotorsports]

@@mayk3lll thank you for the questions because it helps me answer and it’s an answer maybe for a lot that don’t comment too! Plus it helps me understand what other info is good to share Like now? We can expect next episode il double the info shared especially on head inspection 😂 and also Ofcourse during the final assembly Knowing “this” is where we coming from

[@MrSkeeter1505]

Can you make a video on how you seat piston rings? And how you break in an engine.? Thanx Great videos man.

[@SRDmotorsports]

thanks for checking this out man! And great suggestion… though it’s just something I can write and talk about in a span of 2-3mins… then come to think of it… This B20vtec project or an upcoming d16 project I can actually dedicate a specific video that covers exactly what you talked about and relating it to a proper “build” assembly Great suggestion man!! Gonna do this fo sho

[@heryyurie7775]

Should i reuse head srut nut for b16a head at b20b block?

[@SRDmotorsports]

It’s too short for a b20/b18 application Need either a TypeR or ARP head studs

[@heryyurie7775]

@@SRDmotorsports tq for information ..because i just convert my b16a to b20b in progress.

[@SRDmotorsports]

Oh you will enjoy this new power :) just always drive safe

[@CarlosReyes-jj5uz]

did this engine have any piston to valve clearance using clay before when it was first built?

[@SRDmotorsports]

didn’t check cuz it’s just a gsr cam and the 1Up pistons sit 0.030” below deck and the valve pockets are “bigl it’s an Arias dome based design

[@StraightOutThaGudda4U]

Damm no compression on all 4 cylinders? First thing I thought was bent valves and I was right lol

[@SRDmotorsports]

Yes sir! But the owner just said needs a rebuild cuz he experiencing power loss 😂🤣

[@StraightOutThaGudda4U]

@@SRDmotorsports 😂 it needs more than a rebuild

[@marvinreyes6270]

Sir ask lang po anu po pinag kakaiba ng b16 head ang code pr3-3 pr3-4 pr3-2

[@SRDmotorsports]

Just manufacturing generation, all same head the later head has more core shift kaso sa pinas un mas mahal kase mas bago “daw” lol

[@FilthyHeathenKustoms]

Heck yeah can't wait to see what it throws down when your done. Was base timing still set when you did a compression test or did it jump time? Also I like venting from the valve cover vs the back of the block less likely to fill up your catch can with oil

[@SRDmotorsports]

Yes sir brother! I’m as excited! And yep distributor timing is good and I did check the camgears/belt it didn’t jump so it was a weird scene… I hear ya on venting and that’s a good observation and yes both works good

[@SRDmotorsports]

I’m also excited to see if we can improve it more and IF the owner decides to dyno this? Definitely you guys are the first to know :)

[@FilthyHeathenKustoms]

@@SRDmotorsports hopefully he will get it dyno turned. Love my B20v

[@FilthyHeathenKustoms]

@@SRDmotorsports also curious on what numbers he will make. My set up I B20 block bored to 84.5mm high comp pistons, speed factory rods, acl oil pump and bearings, b16 head doubled up on exhaust side valve springs with gsr camshafts, stock intake with 70mm skunk 2 TB mounted to a b16 trans. I don't know what power it makes cause I street tuned it

[@SRDmotorsports]

@@FilthyHeathenKustoms oh definitely I’m hoping to and if he does, il try to put a few tricks up in there to help efficiency ftw

[@marvinreyes6270]

Sir sa b20 po anu mas okay para lumakas b16a head or b18 gsr head

[@SRDmotorsports]

Both pwede lumakas madaming “depende”

[@renwod576]

Do GSR c1 cams have more lift and duration than the b16a? How about compared to b16a2? Very informative and quality to detail vids

[@SRDmotorsports]

actually we did the b16a vs CTR comparison and degreed so on this series il degree this b18c1 and we can compare all 3… I don’t have a b16a2 sadly But I believe the GSR is supposed to be closer to the 96-88 ITR but the ITR having the edge But I am uncertain on that but I’m sure we will find out this B18c1 soon :)
